DAVID S. JACOBU, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO THE BABCOCK 86 wILdox COMPANY,

OF BAYONNE, NEW JERSEY, A CQRPORATION OF NEW JERSEY.

STEAM-BOILER SUPERHEATER.

To all whom it may concern Be it known that I, DAVID S. JAcoBUs, a citizen of the United States, residing in Jersey City, in' the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Steam- Boiler Superheaters, of which the following is a specification. p

My invention relates to steam boiler superheaters, one feature of which is a core designed for superheaters having vertical tubes, or: tubes so inclined that the cores downward.

The invention will be understood by reference to the accompanying drawings in Figure 1 is a front view of a portion of a superheater showing some of the tubes and parts of'the two cross boxes; Fi 2 an end view with tion; Fig. 3 an enlarged view of a part of Fig. 2, partly in section, to show the construction and arrangement of the cores; and Figs/L and 5 are enlarged cross sections on the planes of the lines 4-4 and 5-5, respec-.

tively, of Fig. 3. 7

Similar reference numerals indicate simi lar parts in the several views.

Referring to the drawings the numeral 1 designates U- haped superheater tubes having their lower ends expanded into cross boxes or headers 2 and 3, such construction being one well-known. Opposite "the tube ends are hand-hole openings closed by fittings 4. These fittings are introduced into the hand-hole openings from the inside of the boxes, the practice being to provide the ends of the cross boxes with large openings to permit of the insertion of the fittings The means herein described for support- 7 ing the core is applicable to those made up of a. continuous section or one made u of separable sections. For the purpose '0 describing one application of the invention have shown cores of separable sections and when so made the sections are preferably joined together by a screw connection 6, thus doing away with the use of small pieces, such as screws or pins which are aptto become loose and to e carried along with the steam, which would involve danger to the valves in the steam mains and to the steam Specification of LettersBatcnt.

engines or turbines. Each core is flattened at intervals, as indicated at 7 to provide projections at opposite points in the diameter to hold the core in the center of the tubes. The flattened parts are shown as in planes at right angles to each other, but they may be at any other desired angle. The cores may be solid or hollow as desired.

The lower end of each core is provided with a tail piece 8 which forms a support for the core, and is of such form that it is adapted to rest upon the'bottom of the corresponding cross box at the side of the hand hole fitting 4. The cores are introduced or removed by passing them through the hand holes, and the flexibility of the cores combined with the flexibility of the tail pieces, together with any lost motion between the cores and the tubes, allow the tail pieces to pass to the side of-the hand hole openings a suflicient distance to clear the fittings, that is, the tail pieces 8, when the cores are inserted, are'out of line with the centers of the cores. The hand hole fittings may thus be introduced with thecores in place, and may also be removed without disturbing the cores.

What I claim and desire to secure by Letters Patent of the United States is 1. A superheater core having a supporting hand-hole fittings, and cores in said tubes having supports adapted to rest against the box between the said fittings.

4. A superheater core made up of separable sections and supported by a piece which rests atthe side of a hand hole fitting opposite the core.

5. A steam boiler superheater comprising tubes connected to boxes, said boxes hand'hole fittings, and cores in said tubes made up of separable sections and each core having a support resting at the side of the fitting opposite the core.

6. A superheater core made up of separable sections and provided with a flexible end jections made adapted to be sprung to one side of the opening intheheader box through which the core is introduced so that the end will clear the fitting used for closing the opening and serve to support the core.

'7. A superheater core made up of separable sections Screwed together and provided with a flexible end adapted to be sprung to one side of the opening in the headerbox through which the core is introduced so that the end will clear the fitting used for closing the opening and serve to support the core.

8. A superheater core made up of separaable sections fastened together and provided with projections to keep it in a central position with respect to the tube.

9. A superheater core made up of separable sections and fastened together with screw joints and provided with projections to keep it in a central position with respect to the tube.

10. A separable superheater core provided with screwjoints and in which each piece is ormed of a single piece of metal, with pro- ;,ections made by flattening the core for keeping it in a central position in the tube.

11. A separable superheater core provided with screw joints and in which each piece is formed of a single piece of metal, with proby flattening the core for keeping it in a central position in the tube, and supported by a flexible end which rests at the side of a hand hole fitting in the header box opposite the core.

12. A core for steam boiler 'superheaters consisting of separable sections, the lower naoaeae section having a flexible support secured thereto.

13. A core for steam boiler superheaters as consisting of separable sections and provided with projections to maintain it in a central position with respect to the tube.

14. A core for steam boiler superheaters consisting of separable sections having a as screw connection.

consisting of separable sections, and means 55 on some of sald sectlons to malntam the core in'a central position with relation to the superheater tube.

17. A core for steam boiler superheaters,-

consisting of separable sections having in- W terfitting end connections.

18. A core for steam boiler superheaters, consisting of separable sections having interfitti-ng end portions, and projections on some of said sections arranged to coact with the tube of the superheater to hold the core in fixed relation thereto.

In testimony whereof I have "hereunto signed my name in the presence of two subscribing witnesses.
